Kinect -> Orbbec: The Femto Family

vvvv gamma question

Good question, @maxs, actually I haven’t tried it yet.

Search your error I came across this post by Orbbec . It concerns running bodytracking with Unity but it seems like its another forensic copy-paste job.

Well it seems like you got this covered @Hadasi :)

I wanted to add that we recently discovered the Bolt in particular seems to have an issue where it jumps from USB 3 to USB 2 and introduces a lot of lag. So far there seems to be no known fix: Femto Bolt sensors frequently appearing connected as USB2.1 while using USB 3.1 ports · Issue #45 · orbbec/OrbbecSDK · GitHub

We ended up switching to a Femto Mega which so far has not shown the problem.

As for the BodyTracking, I have not tried it myself, but I have come across this document which lists a few extra steps involving the registry, it might be related (read sections 2 and 3): https://orbbec.github.io/OrbbecSDK-K4A-Wrapper/src/orbbec/docs/Access_AKDK_Application_Software_with_Femto_Bolt.pdf

Give it a try and let us know how it goes :)

To continue adding to this, it seems that the USB issue is only happening on AMD machines.

I have the strange issue, that on one pc here in the studio the Femto Bolt is working in the standard Kinect DSK Viewer, but not inside VVVV. Getting this warning:

Seems not like an Orbbec issue, but a overall windows-.net-something issue. Any ideas what i need to reinstall or update?

Hello there,
I tried to use a femto mega and I followed the instruction of @Hadasi but nothing happen in vvvv … liked no camera was connected…
I do have all the feed back in the k4viewer.exe
I install the driver, I have copied the dll in the nuget file, I used the win x 64 for the sdk…

Other question, is there a plan to developpe the use of this camera throught the Poe connection (big advantage for long cable installation)

Thanks you :)

Hello,
just to let you know
i managed to get the AzureKinect.Body working with the Femto Bolt using:

  • Orbbec Release v1.10.16
  • OrbbecSDK-K4A-Wrapper running the obsensor_metadata_win10.md commands in powershell
  • CUDA V11.2
  • cuDNN 9.6.0 (not sure if it’s mandatory)
  • Azure Kinect Body Tracking SDK v1.1.2
    and the dll copy-paste from OrbbecSDK-K4A-Wrapper to MS Azure Kinect Body Tracking SDK
